What went wrong: Execution failed for task ':app:processDebugResources'. java.io.IOException: Coul

React native  在运行时报以下异常:

* What went wrong:
Execution failed for task ':app:processDebugResources'.
> java.io.IOException: Could not delete path 'F:\RN\RN_Project\AwesomeProject\android\app\build\generated\source\r\debug\android\support'.* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.BUILD FAILED

解决办法:

  用Android Studio 打开该项目 然后点击run 和app左边的那个锤子 按钮, 重新编译程序, 重新用命令行运行该程序即可,切记不要用Android Studio 直接RUN,程序会跑不起来!

 采用cmd命令号,输入 react-native run-android 回车即可!
